If you must use PC Anywhere to enter your network:

1. Install it on a computer that requires a secure login to your
network and computer. NOT Windows 98, where the ESC
key bypasses the logon.

2. Have your Firewall configured to allow 2 'alternate' ports to
pass through (to the PC A enabled puter). Default ports are 5631/5632. Change them !!

3. If it's behind a Firewall, PC Anywhere does not advertise it's
presence making it harder to detect.

The user MUST know the IP address, and the alternate ports to enter the system. Then they must first pass the PC Anwhere security and then the Network Logon.
